How to stop certificate errors temporarily with WCF services

Question

I am testing an early release of a WCF web service I have created. On the client side when I use VS to \'add service reference\' that all works.

But when I try to us

Answer 1

Set the CertificatePolicy PRIOR to initializing your WCF service on the client. Here's how (just make a call to the SetCertificatePolicy() method once)

 /// 

    /// Sets the cert policy.
    /// 
    private static void SetCertificatePolicy()
    {
        ServicePointManager.ServerCertificateValidationCallback += ValidateRemoteCertificate;
    }

    /// 

    /// Certificate validation callback 
    /// 
    private static bool ValidateRemoteCertificate(object sender, X509Certificate cert, X509Chain chain, SslPolicyErrors error)
    {
        if (error == SslPolicyErrors.None)
        {
           return true;   // already determined to be valid
        }

        switch (cert.GetCertHashString())
        {
           // thumbprints/hashes of allowed certificates (uppercase)
           case "066CF9CAD814DE2097D368F22D3A7D398B87C4D6":
           case "5B82C96685E3A20079B8CE7AFA32554D55DB9611":

              Debug.WriteLine("Trusting X509Certificate '" + cert.Subject + "'");
              return true;

           default:
              return false;
        }
    }
